polyembryonic cannabis seeds what to do

Are seedling twins a sign of polyembryonic cannabis?

A new to me term I learned recently while planting mango seeds, polyembryonic. Supposedly these seedlings are exact replicas of the parent plant while other mango seedlings not displaying this expression have more random genetic recombinaions in the prognency.

I couldn’t help but wonder if the occasional twins seedling phenomenon seen in cannabis is a polyembryonic thing like in mango varieties.

From another cannabis website:

TWIN SEEDLINGS
This mutation is very common. Polyembryonic seeds contain more than one seedling. Once germinated, it will produce two taproots instead of one. If carefully handled, these seedlings can be successfully separated into two plants. Strangely, one of the two plants will be a normal offspring of both mother and father. The other plant will only be a clone of the mother. Three-seedling polyembryonic seeds have also been reported. Despite its interesting biological marker and outcome, there is no real advantage to breeding plants with this trait. No effort has been made thus far to develop a true-breed with these characteristics.

Thanks for adding to the discussion everyone, I appreciate the links and observations.

Kryppler, you mention observing a male and female plant out of the twin seedling. When researching and reading around, it seems to be more common than not that when twin cannabis seedlings emerge one is male and one is female. How cool would it be if these are replicas of each parental input! A female copy and a male copy of the genetics. I wonder if there would be a chance for that happening in polyembryonic cannabis seedlings.

Great pictures, Cannafish! Were the pics taken with a phone or camera?

Hi CannaFish, from what I am reading about this phenomenon in seedlings it may very well depend on the variety and how the genetics have been stacking or selected over time up until the point that indiviudal seed is made. Sometimes it’s two seedlings called a duplet, others it may be a three (triplet) or more. Some publications, not specifically speaking of cannabis, mention that sometimes these multiple seedlings are exact copies of a parent plant while other times they differ from the parent plant but are identical to one another. Sometimes, one is different and another identical to the parent. It seems like there is a good bit of variability, but how that translates to cannabis I haven’t been able to find published literature on the subject yet apart from observations like yours and others across the various cannabis forums.

Neat plants you have there, not only multiple seedlings from one seed but whorled or trifoliate or whatever it’s called too. I always seem to confuse the terms. Fascinated by the fasciated specimens, multiple seedlings. Keep them coming! Stoked and staying tuned.

Twin Seedlings

From a second cannabis website:

We’ve been having trouble getting a consensus on the matter of polyembryony in cannabis. There is research in other plants such as oranges and mangos which show that a pair of twin, or polyembryonic seedlings from a single seed will prove to be 2 completely differing cultivars; one being of heterozygous lineage of the two parent plants and the other seedling will be a direct “clone” match of the mother plant. From my reading, I have found that It is used often for mango, citrus and other cultivars to get true to type fruits and plants, and I have also read online that this is true for cannabis.

I carefully separated the two seedlings into their own pots, labeled them and vegged them out, took clones, and put them into flower. The entire time they grew similarly, but had completely different stem rub smells; one was more basic cannabis vegetation with a light orange hint to it and the second is more of an intense burnt rubber and orange peels kind of smell. Once put into flower I quickly realized, not only were they starting to completely deviate in structure, but I had one male plant and one female plant. Remember, these both came from a single seed.

From a third cannabis website:

Some cannabis seeds can germinate two plants. Technically, this is a phenomenon known as polyembryony. This happens just as in the human species. In this case, however, one plant will be normal and one will be a clone of the mother. Like with human conjoined twins, you cannot separate these plants too early. They can be separated when they reach between 20-25cm in height. This phenomenon should not be confused with real “Siamese Twin” marijuana, which is a mutation in which two plants share the same root.

Disclaimer: I have no idea if any of this is true. I do not know where these people are getting their information. I have never seen a ‘twin seedling’ though I suppose it is only a matter of time before I do. For entertainment purposes only. Like stringbeanonna mellow said, I have not been able to find any scientific research on this.

Twin seedlings
Another common mutation found in cannabis is polyembryonic seeds. Polyembryonic seeds contain more one seedling, and when germinated, will surprise their owners by putting out two taproots instead of one.
If carefully handled, it should be possible to remove the seed casing after a day or two and gently separate the two seedlings. Once separated, the two seedlings should happily grow into two healthy plants—and interestingly, while one of the two plants will be the normal offspring of its mother and father, the other will be a clone of its mother.
Although two seedlings are more common, some three-seedling polyembryonic seeds have also been observed. However, while this is an interesting mutation, it does not confer much advantage to the breeder, and apparently no effort has been made to develop a true-breeding polyembryonic strain.

Thank you. I was reading a post where someone let them grow together, i think I’m gonna do that, bending them in opposing directions.

I think the root hairs will get damaged, I’m not going to mess with them. I’m 85% decided about dwc’ing them, that way there would be plenty of room for the roots.

That’s amazing! So will one of these twins be whatever momma was?

Just found out this morning that cannabis seeds can produce twins!

it's like an instant topping, 2 main stems from the jump..

they are two different plants with two different roots, it isnt 2 main stems, it’s 1 main stem for both plants lmao

I get headband seeds from drgreenthumb.com every year. and about 10% of them do this every year.

Hmm that's interesting! Maybe it's the strain.

These are from Humboldt Seed Organization! Are you normally able to save both seedlings?

is this a first?

I'm hoping I can transplant it and get both plants to grow 🙂

Happens sometimes, it's only happened to me once.

Are these regs? Curious to know if they both turn out the same sex.

They are feminized 707 Headband so I'm pretty stoked. My 3-pack might've just turned into a 4 pack lmao

I wonder if they will be fraternal or identical? Is this bagseed or feminized? I'd be curious to see a follow-up post down the line. Are you planning to try to keep both plants?

*Edit glad ur keeping both! Pls update us!

This is feminized 707 Headband from Humboldt Seed Organization! I successfully separated them so hopefully they both grow 🙂

This actually just happened to me too, a seedling hit day 1 and a day later a twin sprouted, I separated them and they are doing great now ❤️❤️

well that's lucky!

“TWINNS BAZZLE, TWIIIINNSSSS”

This isn't the first time this has been posted (really cool and rare though OP!!).

Are these guys generally genetically identical or different – identical vs fraternal twins so to speak.

Joking. Congrats on the twosies. Good luck!

Or you planted two seeds.

Here's some more info:
